Application filed December 31, 1813. Serial Ito. 89,557,

in the construction and functional capabilities of devices of that character wherein buckets and pumps are combined in such a way as to be effective both as storage containers and pumping appliances.

Devices incorporating or embodying the distinguishing advantageous characteristics of my invention have their bases and sidewalls so constructed and associated together as to provide a structure of marked strength and unlikely to leak, even though dented or damaged.

A further object of the invention is the provision of pumping-means which is easily operated, which will deliver measured quantities of the liquid, and the actuation of which will not tend to displace the bucket on the floor, even though it is unattached.

The appliance is also equipped with a novel form of cover, which, while readily operable, cannot be taken off, and aflords a support for the hose nozzle, permitting drainage back into the bucket.

The manner of attaining these and other desirable objects by means of this invention will be readily apparent to those skilled in this art'from a consideration of the desirable embodiment of the invention illustrated in the accompanying drawings forming a part of this specification which should be considered in connection with the following detailed description of the appliance.

In these drawings, like reference characters refer to the same parts throughout the various figures.

In these drawings:

Figure 1 is a vertical central section through the appliance on line 11 of Fig. 5, with the pump turned;

Fig. 2 is a horizontal section on line 22 of Fig. 1;

Fig. 3 is a fragmentary vertical section through the base-portion of-the appliance on line 33 of Fig. 2;

Fig. 4 isa detail view of the plunger-actuating mechanism, and

Fig. 5 is a plan view of. the structure.

By reference to the drawings, it will be observed that the bucket or container comprises a sheet-metal side-wall member 10 of general inverted conical shape. The bottom of the receptacle is composed of an integral cast-metal member 11 having four supporting feet 12, 12. This part 11 has an upstanding, cylindrical, marginal flange 13 just inside of which is an annular groove 14 accommodating the lower edge portion of the shell 10, the latter being fastened to the flange by means of a number of rivets 15, and, in order to insure against leakage under all conditions, such shell or casing is soldered to the base at 16 internally of and entirely around the container so that bending or marring of the shell will not break the solder joint and the device as a whole will be maintained leak proof.

The base also has a central, depending cylindrical socket 17 in register with which there is an upstanding extension or flange 18, the two alined parts 17 and 18 unitedly forming a socket or cavity accommodating the lower portion of the pump barrel or cylinder 19, which extends upwardly through the bucket cover as shown. Base 11 on its under side is equipped with a thickened portion 20 extending outwardly between a pair. of the 23, as is shown. The inner end of passage 21 is in communication with the interior of the socket or chamber 17, 18, and at 2 4 the bottom-wall of the base is depressed, and at this part of the appliance the wall of the socket 18 is apertured at 25. (Fig. 3).

The lower end of the pump barrel or cylinder 19 is equipped with a port 26, which, by turning of the barrel, may be moved into register with the passage 25 or with the passage 21, and, in order to limit such angular turning of the barrel, the latter is provided beneath the wall 11 with a slot 27 into which a pin or screw 28, extended through the wall of the socket 17, projects, such screw or pin constituting a fixed limiting stop, as will be readily understood.

The upper end of the pump-cylinder is sup lied with a bracket member 29, which at its ower end has a cylindrical portion 30 fitted 'in the up er end of the shell 19 and secured therein y a plurality of screws 31, such part of the bracket having a slot 32 for the accommodation of a sliding ratchet pluner rod 33 square in cross-section and carrymg at its lower-end the plunger or piston 34, one edge of such rod being provided with spaced ratchet notches '35 equally distant apart. The upper portion of the bracket has a bearing 36 for such rod or bar, the latter at its upper end being equipped with an operating-handle or finger-grip 37 The appliance also includes a lever 38, supplied with an actuating handle 39, bifurcated so as to rovide two arms 40, 40, which straddle t e bracket and rod and are fulcrumed to the former at 41. Between thei arms 40 a pawl 42 is pivoted at 43, such pawl or finger being yieldingly pressed toward the notched side of bar 33 by a coil expansion spring 44 housed within a cavity of the lever 38. This pawl has a shoulder 45 adapted to cooperate with a ledge or shoulder 46 on that portion of the bracket having the bearing 36. When the handle 39 is raised to its limlt of upward movement, the pawl will become caught on the catch 46 and hold the handle in this elevated position and the pawl out ofcoiiperative relation with the notches of the piston rod, as shown in Fig. 1. Depression of the handle automatically releases the pawl so that it may co-act with such notches.

As is customar in the construction of buckets or pails, t e top edge ofthe sheetmetal wall constituting the shell 10 is bent outwardly around a wire 47 to provide a smooth finish for the top edge. The cover comprises two overlapping sheet-metal members 48 and49, each of which is perforated for the reception of the pump barrel 19 and each of such membersaround its edge is bent downwardly and partially;1 around the marginal rib at the top of t e shell 10. This construction permits the cover members to be moved or swung around on the top of the bucket so as to provide a substantial opening between them or to entirely close the bucket,

the upper member of the cover riding on the under one and the latter in turn riding on the top edge of the bucket. When in the full line position shown in Fig. 5, these two members close the bucket, and when the upper one is shifted to the dotted line position of Fig. 5,

the bucket will open. .55

In order to provide a holding means for the hose nozzle when not in use and to permit the drainage of its contents into the bucket, the cover-member 48 is supplied with an aperture 50 into which the nozzle may be fitted, as shown in dotted lines in Fig. 1.

An appliance of this character, while not limited to any particular use, is, nevertheless, especially adapted for employment in connection with automobiles and similar structures to supply their transmission or differential gear casings with lubricating oils or soft greases.

The appliance 1s operated substantially as follows:

Assuming that the bucket contains a supply of the lubricant and that the plunger -or piston and its rod and handle are at their lowermost position of stroke, the operator,

by means of the handle orgrip 39 turns the pump barrel 19 and its associated parts to the right, bringing the port26. into register I with the aperture25, that is to say, the pump cylinder is brought into communication-with t e interior of the bucket, with no communication with the passage 21. The handle 39 is then lifted its full extent of travel to the positlon shown in Fi 1, the pawl engaging the catch shoulder w ich holdsthe pawl 42 retracted, the latter maintainingthe handle or lever in this elevated osition.

By graspingthe hand e 37, and pulling directly upwardly, the piston or plunger 34 is raised its full stroke and the barrel 19 becomes filled with a charge of the lubricant received from the bucket through the registering apertures'25 and 26. it

Then by means of the handle 39, the operator turns the pump cylinder and its associated parts to the left, breaking communication between the interior of the bucket and the pump barrel and establishing a connection between the barrel and the passage 21 and the hose connected thereto.

Now, the lever handle 39 isdepressed and moved downwardly its full extent of move- Fig. 4. At the beginning of this movement the pawl passes away from its retaining shoulder 46 and soon afterward automati-'=- cally engages the lower-most ratchet notch of the piston rod 33 so that continued 'depression of the handle forces the plunger down and discharges through the hose and nozzle a definite measured quantity of the and directly into the desired receptacle, the

discharge being accurately measured as delivered.

Ifi't should be desired to handle a lubricant of a different quality or character from that contained in-the bucket, the nozzle or hose is inserted into the can of the desired kind of ease or oil and the barrel or chamber of t e bucket may be drawn full of the foreign lubricant, which is subsequently dis- 100 ment to the position shown in dotted lines in v be quickly removed from the difierential or transmission casing of an automobile and delivered into a third receptacle for preservation for future use. This eliminates the disagreeable task of removing the grease by hand when it becomes necessary to inspect or overhaul these parts of an, automobile and it also does away with a considerable waste of the lubricant ordinarily occasioned by such action.

By employing an appliance embodying this invention the drippin of the grease or oil is prevented and the Iubricant is accurately, economically, and quickly handled. It should be. observed that the discharge is accomplished by an easy downward pumping stroke of the lever handle which can be readily operated with' one hand, leaving the other hand free to guide the hose nozzle, and, owing to the construction and arrangement of arts, there is no tendency to shift the hue et on the floor or upset it, and there is no requirement for keeping it in place by the foot, either in filling-the pump barrel with the oil or in discharging it, both of these operations requiring a practically-vertical movement of the working parts.

It should be noted further that by making the base of the bucket in one integral casting and by riveting and soldering the side-wall in place leaka e is entirely avoided, even though the app iance itself may be more or less damaged. p

The cover constitutes an improvement and allows the container to be easilyfilled with grease, the cover not being easily broken ofi or removed, and not sub ect to loss or displacement.

I claim: 1. In an appliance of the character described, the combination of a bucket-body, a bottom therefor composed of a single casting having a socket, a passage leading from the interior of the bucket to the interior of the socket, and a passage from the interior of the socket to the outside of the bucket adapted to have a hose connected thereto, a
